Burr vulnerable, but leads possible challengers

A new poll shows incumbent Richard Burr leads potential Democratic challengers in the race for US Senate next year. But pollsters also say he is in about the same position Elizabeth Dole was before she lost to Kay Hagan.

Public Policy Polling found only former State Sen. Cal Cunningham, when respondents heard his two-sentence biography, was within eight points of Burr. Based on name recognition alone, Elizabeth Edwards and State Sen. Dan Blue were 11 points behind.

In a poll last month, Rep. Mike McIntyre trailed Burr by just five points.
